Observing Bacteria and Blood Student Jamie Chrostowski Lab 1 – Due 2/15/15 Microbiology DL1, Professor Newton Abstract: The different objectives of a microscope allow for a range of observations. At the highest objectives, the resolution can easily be lost which is why the oil immersion lens is used to minimize refraction. While observing specimens, both dead and active, their shapes and arrangements can be observed. This allowed for hands on learning, observation, and identification of the bacterial

Today, anyone can go to the grocery store and purchase fruits and vegetables that have been genetically modified. As a matter of fact, most of us do it unknowingly all the time. But, what exactly are genetically modified foods and what sets it apart from traditional breeding? The biotech industry and our departments of agriculture claim that genetic engineering is a natural extension of traditional breeding. However, traditional agriculture methods, such as cross-pollination or selective breeding,

DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules

With Anton Van Leeuwenhoek inventing the microscope, Edward Jenner pioneering vaccines, and Louis Pasteur discovering germs (Rhodes, 2014), it was obvious that science was beginning to advance in the 18th and 19th centuries. Today’s “common knowledge” was just being discovered during that time period. People were curious how things worked and how to improve the lives of others. Even though it took a while for a theory to be accepted in the scientific community, little was known about science or microbiology

The bacteria campylobacter was discovered in 1886. Escherich is the one who got the bacteria from children who had diarrhea. McFadyean and Stockman found campylobacter from fetal tissues in 1913. According to the article Campylobacter Jejuni- An Emerging Foodborne Pathogen, it said “The development of selective growth media in the 1970s permitted more laboratories to test stool specimens for Campylobacter.” Over the period of time more and more laboratories were went to test Campylobacter. Campylobacter

In order to identify the predation functional response of H. axyridis to tea aphids, the experiment was conducted in the controlled environment incubators (16-hr-light photoperiod; 25±3°C; 70±3% RH). The tea aphids used in this experiment were young nymphs. One first instar, starved for 24h, was placed into Petri dish (diameter 9cm and height 2cm) with a soft writing brush, tea aphids along with fresh host plant leaf were also provided. The open end of Petri dish was covered with porous pvc film
